Cursor 3 Redefines Agent-First Development, GitHub Opens Copilot SDK, Claude Dispatch Bridges Phone to Desktop
- Cursor 3 — April 2, 2026. Agents Window across local, worktrees, cloud, SSH; Design Mode;
/worktree,/best-of-n; MCP Apps; Composer 2 at $0.50–$1.50 per million input tokens. - GitHub Copilot SDK — Copilot plans: Free (2,000 completions, 50 chat/month), Pro $20/month, Business $30/user/month (300 premium requests), Enterprise $39/user/month with Claude Opus 4.6 access.
- Claude Dispatch — Phone-to-desktop continuity; extends Claude Agent SDK already in Apple Xcode (Feb 3, 2026).
- Theme — Developer tools redesigning around persistent, portable AI workflows.
April 3, 2026 evening tracks three developer-focused stories: Cursor 3 doubles down on agent-first design, GitHub opens the Copilot SDK, and Claude Dispatch bridges phone-to-desktop workflows.
Cursor 3 Redefines Agent-First Development
Persistent agent workspaces replace autocomplete-centric IDE layouts
Cursor · Released April 2, 2026
Cursor 3.0 completes the pivot from autocomplete-centric IDE to agent-first environment. Documented features from the April 2, 2026 release: the Agents Window for running multiple agents across local, worktrees, cloud, and SSH; Design Mode for UI annotation; Agent Tabs; the /worktree and /best-of-n commands; MCP Apps with structured content; enhanced large-file diff rendering; and Composer 2 priced at $0.50–$1.50 per million input tokens. The April 8, 2026 Bugbot update followed with a reported 78% resolution rate and Learned Rules.
Tech Analysis
Cursor 3 treats the IDE as a coordination surface for human-agent collaboration. The bet is that task queues and multi-file review become standard IDE primitives, forcing JetBrains and Visual Studio to follow.
GitHub Opens Copilot SDK
Third-party tool builders gain programmatic Copilot integration
GitHub · April 3, 2026
GitHub opened the Copilot SDK, enabling third-party tool builders to integrate Copilot capabilities into their own products. Published plan matrix: Free tier (2,000 completions + 50 chat requests per month), Pro at $20/month with Anthropic, Google, OpenAI models and cloud agent, Pro+ adding GitHub Spark and Claude Opus 4.6, Business $30/user/month with 300 premium requests, and Enterprise $39/user/month with access to all models including Opus 4.6 and audit logs. Agent mode analyzes code, proposes edits across multiple files, runs tests, and validates results autonomously.
Tech Analysis
Opening the SDK expands GitHub’s reach beyond its own UI and positions Copilot as a platform. Expect dev-tool vendors to embed Copilot alongside their own agent runtimes, blurring Copilot-vs-Claude-Code distinctions.
Claude Dispatch Bridges Phone to Desktop
Mobile Claude sessions continue on desktop with full context
Anthropic · April 3, 2026
Claude Dispatch lets users start on a phone and continue on a desktop Claude Code session with preserved context. The capability rides on Anthropic’s Claude Agent SDK — the same SDK Apple adopted in Xcode on February 3, 2026 — and pairs naturally with Sonnet 4.6 (Feb 17, 2026, 1M-token context beta, $3/$15 per million tokens).
Tech Analysis
Device-portable AI context is a form of the stateful agent pattern. Dispatch makes Claude’s context a first-class object that follows the user rather than the device — what enterprise adoption demands.
